The syndrome of intrathoracic voltage (SITV) in children is a difficult complex of the symptoms, that manifests a mono- or combination increasing of intrapleural, intrapulmonary or mediastinal pressure resulting from the accession of complications with different surgical (BDL, trauma of chest, lobar emphysema, diaphragmatic hernia, which is complicated by pulmonary bulla and cyst ) and somatic (spontaneous pneumothorax in bronchial asthma, tense pleuritis in glomerulonephritis, diseases of the spleen) diseases.

rapid deterioration in lung ventilation on the affected side and healthy side;

displacement of the heart and mediastinal vessels, along with a healthy side;

hypertension of small pulmonary circulation;

abnormal shunting of blood from the right (normally up to 5%) - in to the left;

formation of an acute or chronic hypoxia, central nervous system and entire body;

development of the pleuropulmonary shock;

risk of sudden cardiac arrest and breathing.

-The frequency of SITV is determined during the life by frequency of complications, by the spread of the underlying disease, by the age of the child.

- In the case of a unilateral lesion by SITV of child's body - the main objective diagnostic criterion (chest X-Ray, ultrasound, cardiogram) is the suddenness and speed of dislocation of the lateral borders of the heart and mediastinum to the healthy side against the background, mainly severe acute respiratory failure, and cardiovascular failure.

In newborns SITV often occurs as a complication of catheterization of the subclavian veins, aspiration of mucus from the bronchi and esophagus, as well as in spontaneous chylothorax and chylopericardium.

The chest (usually the left side) is swollen, lags behind in the act of breathing.

There are dyspnea, cyanosis, dry and recrudescent cough on the background of normal or subfebrile body temperature, a pathological emphysema of a lung on the affected side with the displacement of the heart in a healthy side and atelectasis of the lower parts of the lungs on the affected side.

Complications (mostly by valve mechanism) occurs in a place of dichotomous division of the bronchi. Often preliminary infection of the cyst helps it (acute respiratory infections, bronchitis, pneumonia).

Clinic is caused of acute pneumonia, suppuration, bleeding and gap of the cyst.

- Breakthrough of the cyst into the pleural cavity: a sudden paroxysmal cough, the child is concerned, there is shortness of breath, fever and tachycardia. Lag of the chest in the act of breathing and increasing an affected half of its. There is a clinical picture of pneumothorax, anemia and SITV.

- The X-ray pictures of organs of the chest show thin sharp contours of cyst.

- Tomogram, X-Rays in 2 projections help to distinguish it from the bula; bronchography, CT, MRI, - from the lung abscess and other diseases.

- Angiography and scintigraphy fix an avascular area on the periphery; in 16% of cases with bronchography the contrast enters the cyst.

Puncture, the cyst micro drainage must be done in cases of contraindications to radical surgical treatment, They are as the stage of diagnosis and conservative treatment (if are danger of gap or of internal bleeding).

Mostly are affected fourth-order bronchi (subpleural, rare can be the central abscess).

Microscopic and clinical-radiological picture are determined by the abilities of viruses to generate exo-and endotoxins, by difference of structure of microfoci, by child's age, by shape and localization of lesions and the overall response of the body in response to aggression.
